BACKGROUND
1. Field of the Invention
The present disclosure relates to a display apparatus, and more
particularly, to a borderless type display apparatus with a
built-in camera.
2. Discussion of the Related Art
Recently, various flat-type display devices, which substitute for
Cathode Ray Tube (CRT), have been actively researched and studied.
For example, Liquid Crystal Display (LCD) device, Plasma Display
Panel (PDP), Field Emission Display Device (FED), Light Emitting
Display (LED) device, and etc. Especially, the LCD device has
attracted great attentions owing to the advantageous properties
such as mass production technology, simple driving means, and high
picture quality.
Recent research and development are particularly being required on
designs of products appealing to consumers. Consequently, efforts
for minimizing the thicknesses (slimness) of LCD devices are
continuously being made, and research is being conducted on a
design with enhanced sense of beauty that can induce consumers to
buy by appealing to consumers' sense of beauty.
In efforts for minimizing the thicknesses of LCD devices and design
development for enhancing a sense of beauty that have been made to
date, however, the existing elements have been applied as is, the
structures of the elements have been changed simply, and thus,
there are limitations in minimizing the thicknesses of the LCD
devices and developing new designs of the LCD devices.
For example, a related art LCD device necessarily uses lower and
upper cases to receive a liquid crystal display panel and a
backlight unit therein. In addition, front and rear set covers are
additionally used in the related art LCD device to manufacture a
product such as a notebook computer, a monitor, a mobile device, or
a television.
As the lower and upper cases and the front and rear set covers for
the manufactured device are inevitably used, it makes a limitation
in the slimness of the display device and the advance toward the
new design. Especially, the front edge parts of the liquid crystal
display panel are covered with the upper case and the front set
cover, whereby the liquid crystal display device is increased in
its thickness. Also, the border width of the liquid crystal display
device may be increased so that the difference in height of the
stepped portion may cause limitations in advance toward the
innovative design.
Recently, a notebook computer having a camera has been introduced
for a video chatting or video conference. Thus, since an additional
space for the camera is necessarily required in the notebook
computer, a border width of a screen in the notebook computer is
increased more, whereby it makes a limitation in the advance toward
the new design.
In order to overcome this problem, various display apparatuses
without the stepped portion on the plane has been researched and
studied.
In case of the display apparatus having a camera mounted on a lower
side of a panel, a transmitting hole is formed under the
circumstance that black matrix patterns deposited on an upper
substrate of the panel are removed from a portion corresponding to
the camera, whereby ambient light comes into the camera without
being affected by the black matrix.
However, in case of the above display apparatus according to the
related art, there is an empty space between the lower substrate
and the black matrix in the periphery of the transmitting hole. If
the upper substrate is pushed by an external force, a depression
may occur in the periphery of the transmitting hole, whereby mura
defect may occur in a display area adjacent to the transmitting
hole.
As mentioned above, since the display apparatus according to the
related art has the empty space between the lower substrate and the
black matrix in the periphery of the transmitting hole, a
concentric-circle shaped diffraction pattern is generated on an
image taken by the camera due to a diffraction of light passing
through the glass upper substrate and the transmitting hole.

Although not shown, the first panel supporter 204a may have
additional rooms at both sides of the camera receiving part 500,
wherein the additional rooms are similar in shape to the camera
receiving part. In this case, antenna or antenna wire may be
arranged in these additional rooms of the first panel
supporter.
The display unit 300 may include the panel 301; polarizing plates
311, 312, 310; the optical film 309, the light-guiding plate 308,
the reflective plate 307, and the light source 350.
The panel 301 is formed by bonding an upper substrate 301a and a
lower substrate 301b to each other. The panel 301 includes a
display area in which various devices are formed; and a non-display
area which is formed in the periphery of the display area. At this
time, the non-display area is divided into a first non-display
area, a second non-display area, a third non-display area, and a
fourth non-display area. The first panel supporter 204a is placed
on the first non-display area; the second panel supporter 204b is
placed on the second non-display area; the third panel supporter is
placed on the third non-display area; and the fourth panel
supporter is placed on the fourth non-display area.
According as liquid crystal injected between the upper and lower
substrates 301a and 301b is driven by a voltage applied to the
lower substrate, the panel 301 outputs an image in accordance with
a transmission amount of light emitted from the light source 350,
wherein the panel 301 may be formed in various types.
The light source 350 is provided to supply the light to the panel.
In this case, various kinds of light source may be used. Recently,
a light-emitting diode (LED) is used for the light source 350.
The light-guiding plate 308 diffuses and reflects the light emitted
from the light source 350 toward the panel. That is, as shown in
FIGS. 2 and 3, the light-guiding plate 308 is provided in a
side-light type display apparatus in which the light source 350 is
formed at a lateral side thereof, wherein the light-guiding plate
308 guides the light emitted from the light source toward the
panel.
The optical film 309 diffuses the light passing through the
light-guiding plate 308, or enables the vertical incidence of the
light passing through the light-guiding plate 308 on the panel 301.
The optical film 309 may include a diffusion sheet, a prism sheet,
and etc., wherein the optical film 309 may vary in structure.
The reflective sheet 307 is provided on a lower surface of the
light-guiding plate, wherein the reflective sheet 307 reflects the
light emitted from the light source toward the panel. That is, the
light, which is emitted from the light source and is then incident
on the light-guiding plate, is refracted by a pattern on the
light-guiding plate, and is reflected toward the panel. However,
there may be the light discharged to the external through the lower
surface of the light-guiding plate without being reflected. In this
case, the reflective sheet re-reflects the light toward the
panel.
The polarizing film 311, 312, 310 is attached to the plane or lower
surface of the panel including the liquid crystal. The polarizing
film 311, 312, 310 transmits predetermined ingredients of light
according as the voltage applied to the panel is turned-on/off.
Meanwhile, the present invention is characterized by the display
unit 300, especially, the structure of the panel 301. The detailed
structure of the display apparatus according to the present
invention will be described with reference to FIGS. 3 to 16.
FIG. 3 is a detailed cross section view illustrating the display
apparatus according to the first embodiment of the present
invention, which illustrates the detail of portion `D` of FIG.
2.
That is, FIG. 3 is a detailed cross section view illustrating the
display apparatus according to the first embodiment of the present
invention, especially, the detailed cross section view of the
panel.
First, the panel includes the upper substrate 301a, the lower
substrate 301b, and the liquid crystal layer between the upper
substrate 301a and the lower substrate 301b.
The lower substrate is a driving device array substrate. Although
not shown in detail, there are plural pixels on the lower
substrate, wherein each pixel includes a driving device such as a
thin film transistor.
The upper substrate is a color filter substrate, wherein a color
filter layer for realizing color is formed on the upper
substrate.
On each of the lower substrate 301b and the upper substrate 301a,
there are pixel electrodes, common electrodes, and an alignment
layer coated for alignment of liquid crystal molecules included in
the liquid crystal layer.
The lower substrate and the upper substrate are bonded to each
other by the use of sealant formed in the periphery of the
substrate. Between the lower substrate 301b and the upper substrate
301a, there is a space for maintaining a cell gap therebetween.
In the panel 301 having the above structure, the liquid crystal
molecules are driven by the driving device on the lower substrate,
whereby information is displayed by controlling the amount of light
passing through the liquid crystal layer.
In the above structure of the panel, the lower substrate is formed
by a driving device array substrate process, and the upper
substrate is formed by a color filter substrate process for forming
the color filter.
The driving device array substrate process includes steps of
forming a plurality of gate lines and data lines to define pixel
regions on the lower substrate; forming the thin film transistor
corresponding to the driving device, which is connected with the
gate and data lines, in each pixel region; and forming the pixel
electrode connected with the thin film transistor, wherein the
pixel electrode drives the liquid crystal layer in accordance with
a signal applied via the thin film transistor.
The color filter substrate process includes steps of forming a
black matrix on the upper substrate; forming the color filter
thereon; and forming the common electrode.
On the upper substrate of the panel applied to the display
apparatus according to the first embodiment of the present
invention, the black matrix 301k is coated thereon, and the black
matrix 301k is formed in the first non-display area of the panel.
Also, a transmitting hole 301g is formed at a position
corresponding to the camera in the black matrix of the first
non-display area. The transmitting hole 301g may be formed by an
etching process of the color filter substrate process. That is, the
black matrix 301k, the color filter (not shown), and the common
electrode 301c are deposited on the upper substrate 301a, and then
the transmitting hole 301g is formed by the etching process using a
mask. In this case, the transmitting hole 301g is formed when the
black matrix 301k is etched together with the color filter (not
shown) or the common electrode.
On the common electrode or a planarization layer of the upper
substrate, there is the spacer for maintaining the cell gap between
the upper substrate 301a and the lower substrate 301b. Preferably,
the spacer is formed of a column spacer. The column spacers may be
provided on desired portions of the entire surface of the panel at
the constant density. That is, since the column spacers are
provided on the desired portions, the cell gap is constantly
maintained between the lower substrate 301b and the upper substrate
301a, thereby preventing an aperture ratio from being
deteriorated.
On the lower substrate 301b, there may be a protrusion
corresponding to the column spacer. This protrusion prevents a
press defect when the column spacer contacts with the
substrate.
As mentioned above, the column spacer deposited on the upper
substrate may directly contact with the lower substrate so as to
maintain the cell gap between the lower substrate and the upper
substrate, or may contact with the protrusion so as to maintain the
cell gap between the lower substrate and the upper substrate.
That is, the panel 301 is formed by bonding the upper substrate
301a having the column spacer deposited thereon with the lower
substrate 301b.
Thereafter, the edge of the panel 301 is sealed by a seal 301f, and
then the liquid crystal is injected into the inside of the panel
301 via an inlet under the circumstance that the edge of the panel
301 is sealed. Then, the panel 301 is completed by sealing the
inlet.
As shown in FIG. 3, the present invention is characterized in that
the liquid crystal is formed in the first non-display area.
That is, since the liquid crystal is injected into the liquid
crystal layer of the first non-display area 301d, it is possible to
prevent a depression in the periphery of the transmitting hole 301g
of the first non-display area.
Moreover, a refractive index of the liquid crystal is closer to
that of a glass than a refractive index of air or a refractive
index of vacuum. Therefore, when the liquid crystal is injected
into the liquid crystal layer in the first non-display area 301d,
diffraction can be prevented from occurring around the transmitting
hole. Accordingly, a diffraction pattern can be prevented from
being formed on an image that is captured by the camera.
FIG. 4 is a detailed cross section view illustrating a display
apparatus according to the second embodiment of the present
invention, which illustrates the detail of portion `D` of FIG.
2.
Except the inner structure of the panel, the display apparatus
according to the second embodiment of the present invention is
identical in structure to the display apparatus according to the
first embodiment of the present invention, whereby a detailed
explanation for the same parts will be omitted or will be described
in brief.
That is, FIG. 4 is a detailed cross section view illustrating the
display apparatus according to the second embodiment of the present
invention, especially, the detailed cross section view of the
panel.
First, the panel includes the upper substrate 301a, the lower
substrate 301b, and the liquid crystal layer between the upper
substrate 301a and the lower substrate 301b.
The lower substrate 301b in the display apparatus according to the
second embodiment of the present invention is identical in
structure and manufacturing method to that of the display apparatus
according to the first embodiment of the present invention.
Unlike the upper substrate 301a of the display apparatus according
to the first embodiment of the present invention, the upper
substrate of the display apparatus according to the second
embodiment of the present invention is characterized in that column
spacers 301h are formed in the first non-display area 301d. In the
display apparatus according to the second embodiment of the present
invention, a transmitting hole 301g is formed in a black matrix
301k of the first non-display area, and the column spacers 301h are
formed at both sides of the transmitting hole 301g with respect to
the transmitting hole 301g.
For this, after the black matrix, color filter and common electrode
are sequentially deposited on the upper substrate 301a, the
transmitting hole 301g is formed in the black matrix of the first
non-display area by the above process. Then, the column spacers
301h are formed in the periphery of the transmitting hole 301g.
Thereafter, the edge of the display area is sealed by a first seal
301e, and then the liquid crystal is injected into the inside of
the panel 301 via an inlet under the circumstance that the edge of
the display area is sealed. Then, the panel 301 is completed by
sealing the inlet.
As shown in FIG. 4, the first seal 301e is formed along the
interface between the first non-display area and the display area.
In case of the display apparatus according to the first embodiment
of the present invention, the liquid crystal is filled in the first
non-display area under the circumstance that the seal is not formed
between the first non-display area and the display area. In case of
the display apparatus according to the second embodiment of the
present invention, while the first seal is formed between the first
non-display area and the display area, the liquid crystal is
injected only into the display area sealed by the first seal.
Also, the edge of the first non-display area is sealed by a second
seal 301f, and a cell gap is maintained between the lower substrate
301b and the upper substrate 301a by the use of second seal.
For the manufacturing process of the upper substrate, at least one
column spacer is formed in the periphery of the transmitting hole
of the first non-display area, whereby the column spacer is formed
in the first non-display area sealed by the first and second seals,
as shown in FIG. 3.
The column spacer 301h is manufactured by the manufacturing process
of the upper substrate. Since various patterns of the lower
substrate 301b of the display area are not provided in the first
non-display area 301d, there is a constant interval between the
column spacer 301h and the lower substrate 301b.
The column spacer formed in the display area is deposited in such a
manner that a height of the column spacer in the display area is
determined in consideration to the height of pattern layers. Also,
the column spacer 301h of the first non-display area 301d together
with the column spacer of the display area is formed on the upper
substrate 301a. Thus, in case of the column spacer 301h provided in
the first non-display area on which the pattern for forming the
pixel of the lower substrate is not formed, it is formed as a shape
being provided at a predetermined interval from the lower
substrate. However, the column spacer 301h in the first non-display
area may be manufactured separately from the column spacer in the
display area. In this case, a height of the column spacer 301h in
the first non-display area 301d may be determined in consideration
to a height of the cell gap between the lower substrate and the
upper substrate, whereby the column spacer 301h in the first
non-display area 301d may contact with the lower substrate.
As mentioned above, the various patterns for forming the pixel are
not formed in the first non-display area. This is for improving the
efficiency of antenna received in an antenna receiving part of the
first panel supporter for supporting the first non-display
area.
That is, the first panel supporter of the display apparatus
according to the present invention may include not only the camera
receiving part but also the antenna receiving part at both lateral
sides of the camera receiving part. Thus, if receiving the antenna,
the various patterns of the metal material for forming the pixel
may deteriorate the efficiency of the antenna. In this respect, the
various patterns of the display area are not provided in the lower
substrate of the first non-display area.
If the patterns of the display area are provided in the lower
substrate, an additional transmitting hole for transmitting light
to the camera has to be formed in the patterns of the lower
substrate. Thus, the patterns for forming the lower substrate are
not provided in the first non-display area of the display apparatus
according to the present invention. If the patterns of the lower
substrate are provided in the first non-display area for the
manufacturing process of the lower substrate, the patterns may be
removed from the first non-display area by the etching process.
The column spacer in the non-display area is provided at a
predetermined gap from the lower substrate. Virtually, the gap
between the column spacer and the lower substrate is about 0.77
.mu.m which is negligible.
Even though the panel of the transmitting hole of the first
non-display area is pushed by the external force, the column spacer
enables to prevent the depression in the black matrix, thereby
preventing the depression in the upper substrate.
Moreover, since recess is prevented, the gap between the upper
substrate 301a and the lower substrate 301b is not changed.
Therefore, a refractive index between the upper substrate 301a and
the lower substrate 301b is not changed. Accordingly, diffraction
can be prevented from occurring around the transmitting hole, and
thus, a diffraction pattern can be prevented from being formed on
an image that is captured by the camera.
FIG. 5 is a plane view illustrating the lower side of a display
apparatus according to the present invention, wherein (a) of FIG. 5
illustrates a virtually-shown lower side of the display apparatus
according to the first embodiment and second embodiment, and (b) of
FIG. 5 illustrates a perspective view of the panel placed on the
panel supporter and the lower supporter, particularly, the first
seal 301e and the second seal 301f formed inside the panel of the
display apparatus according to the second embodiment of the present
invention.
As shown in (a) of FIG. 5, the peripheral region of the lower side
of the display apparatus according to the first embodiment and the
second embodiment is covered with the guide frame 200.
Meanwhile, as mentioned above, the guide frame 200 is formed
vertically while being in parallel to the set sidewall 102 of the
set cover 100, wherein the guide frame 200 is formed in the
square-shaped frame. The guide frame 200 includes the guide
sidewall 202 which covers the lateral side of the display unit 300.
However, since the guide sidewall 202 protrudes in the opposite
direction to the viewing side from (a) of FIG. 5, the guide
sidewall 202 is not shown in (a) of FIG. 5.
The panel supporter 204, which protrudes from the guide sidewall in
the opposite direction to the set cover, supports the panel.
Especially, the camera hole 208 is formed in the first panel
supporter 204a with the camera receiving part 500 to be provided
with the camera.
That is, the camera receiving part 500 for receiving the camera
therein is formed in the central portion of the first panel
supporter 204a. Also, the camera hole 208 is formed in the first
panel supporter with the camera receiving part. Thus, the ambient
light comes to the camera via the first peripheral portion of the
polarizing film, the panel, and the camera hole 208.
The lower supporter 206 is formed with the stepped portion from the
panel supporter, and the lower supporter 206 supports the
light-guiding plate, the light source, the reflective plate, and
the optical film arranged at the lower side of the panel. At this
time, since the reflective plate 307 is positioned at the lowest
portion as shown in FIG. 2, the reflective plate 307 is placed onto
the lower supporter 206, as shown in (a) of FIG. 5.
For the above explanation about the display apparatus according to
the present invention, the display apparatus according to the
present invention is a liquid crystal display apparatus having the
display unit including the light-guiding plate and the light
source, but it is not limited to this type. Instead, the display
unit may be formed of plasma display panel, a field emission
display apparatus, and a light-emitting display apparatus.
Also, (b) of FIG. 5 illustrates the lower side of the display
apparatus according to the second embodiment of the present
invention. As mentioned above, (b) of FIG. 5 illustrates the
perspective view of the panel placed on the panel supporter 204 and
the lower supporter 206. Thus, (b) of FIG. 5 illustrates the
transmitting hole 301g, first seal 301e, and second seal 301f in
the first non-display area inside the panel applied to the second
embodiment of the present invention.
That is, the second seal is formed in the outermost portion of the
panel, whereby the second seal is formed in the outermost portion
of the entire panel. Also, the first seal is formed along the
interface between the display area and the first non-display area
301d of the panel.
FIG. 6 is a detailed cross section view illustrating a display
apparatus according to the third embodiment of the present
invention, which illustrates the detail of portion `D` of FIG.
2.
Except that the first seal 301e is formed to separate the display
area and the first non-display area of the panel from each other,
and the first non-display area is not filled with liquid crystal,
the display apparatus according to the third embodiment of the
present invention is identical in structure to the display
apparatus according to the first embodiment of the present
invention. Also, except that the column spacer is not formed in the
first non-display area, the display apparatus according to the
third embodiment of the present invention is identical in structure
to the display apparatus according to the second embodiment of the
present invention. Thus, a detailed explanation for the same parts
as those of the first or second embodiment will be omitted. Also,
even though the guide panel shown in (a) of FIG. 6 is different in
structure from the guide panel shown in (b) of FIG. 6, their
functions are the same.
First, in comparison to the first embodiment of the present
invention, (a) of FIG. 6 shows that the first non-display area 301d
and the display area are sealed by the first seal 301e, and the
liquid crystal is not filled in the first non-display area 301d
sealed by the first seal 301e and the second seal 301f.
In comparison to the second embodiment of the present invention,
(a) of FIG. 6 shows that the column spacer is not formed in the
first non-display area.
Except that the structure of the first panel supporter with the
camera receiving part, (b) of FIG. 6 is identical in structure and
function to (a) of FIG. 6.
As mentioned in the above explanation for the first embodiment of
the present invention with reference to FIG. 2, the first panel
supporter 204a may be formed in the `.andgate.` shape or `.orgate.`
shape. In this case, (a) of FIG. 6 illustrates the
`.andgate.`-shaped first panel supporter, and (b) of FIG. 6
illustrates the `.orgate.`-shaped first panel supporter.
The third embodiment of the present invention enables to prevent a
ripple phenomenon from occurring in the panel by the contact with
the first panel supporter.
The third embodiment shown in (a) and (b) of FIG. 6 enables to
prevent a ripple phenomenon from occurring by the interference with
the guide frame arranged in the lower side of the panel.
In addition, among the black matrixes deposited on the upper
substrate, the non-display area including the periphery of the
transmitting hole in the area corresponding to the camera is
isolated by the first seal 301e, and the liquid crystal is not
filled in the non-display area 301d, whereby it is possible to
prevent a ripple phenomenon from occurring in the panel by the
first panel supporter, wherein the first panel supporter supports
the panel while being positioned at the lower side of the
panel.
If the first panel supporter is formed in the V shape, as shown in
(b) of FIG. 6, the above function may be maximized. That is, in (b)
of FIG. 6, the first panel supporter 204a is formed in the
`.orgate.` shape, and thus, the first non-display area including
the periphery of the transmitting hole is not attached to the first
panel supporter 204a. Therefore, interference between the first
non-display area and the first panel supporter 204a does not occur.
Accordingly, a ripple is not generated.
Hereinafter, a display apparatus according to the fourth embodiment
of the present invention will be described with reference to FIGS.
7 to 16.
FIG. 7 is a plane view illustrating a panel applied to a display
apparatus according to the fourth embodiment of the present
invention, which illustrates the plane of the panel 301 of the
display apparatus shown in FIG. 2. FIG. 8 is a detailed cross
section view illustrating a display apparatus according to the
fourth embodiment of the present invention, which illustrates the
detail of portion `D` of FIG. 2. Especially, the cross section of
the panel 301 shown in FIG. 8 is to the cross section along B-B' of
FIG. 7.
The panel applied to the display apparatus according to the fourth
embodiment of the present invention includes the upper substrate
301a and the lower substrate 301b which are bonded to each other
under the circumstance that the liquid crystal layer is formed
therebetween. The liquid crystal layer between the lower substrate
301b and the upper substrate 301a is sealed by the seal formed in
the peripheral region of the panel.
The panel applied to the present invention may be divided into the
display area 360 in which the various elements are formed to
display the image; and the non-display area which is formed in the
periphery of the display area. At this time, the second to fifth
seals 301f, 301m, 301n, 301p are respectively formed at the
peripheral regions of the panel in the non-display area of the
panel, thereby sealing the gap between the upper substrate and the
lower substrate. Also, the first seal 301e is formed between the
first non-display area 301d and the display area 360.
That is, the second to fifth seals 301f, 301m, 301n, 301p are
formed in the outermost portions of the four sides of the panel,
that is, the outermost portions of the entire panel. The first seal
301e is formed in the boundary between the first non-display area
301d of the panel and the display area 360.
Also, in order to make the ambient light guide toward the camera
lens, the transmitting hole 301g made by removing the black matrix
301k is formed in the first non-display area 301d.
As shown in the expanded circle portion of FIG. 7, the first seal
301e is formed in the shape surrounding the peripheral region of
the transmitting hole (hereinafter, referred to as `transmitting
part`). In FIG. 7, since the first seal and second seal surrounding
the transmitting part are connected with each other, the
transmitting part is isolated from the remaining portions of the
first non-display area except the transmitting part (which will be
referred to as `vacuum part`), and is provided to penetrate the
display area.
When the liquid crystal (liquid crystal layer) is filled between
the lower substrate and the upper substrate sealed by the first
seal 301e and the third to fifth seals 301m, 301n, 301p, the liquid
crystal is filled in the transmitting part. At this time, the
vacuum part is sealed by the first seal and the second seal under
the vacuum state.
Meanwhile, the above structure can be shown in FIG. 8 which
illustrates the cross section of the display apparatus according to
the fourth embodiment of the present invention. The cross section
shown in FIG. 8 illustrates the display apparatus according to the
present invention on which the panel including the cross section
along B-B' of FIG. 7 is mounted, especially, the cross section of
portion `D` of FIG. 2.
That is, as shown in FIGS. 7 and 8, the panel applied to the
present invention includes the upper substrate 301a, the lower
substrate 301b, and the liquid crystal layer formed between the
upper substrate 301a and the lower substrate 301b.
The upper substrate 301a, lower substrate 301b, and liquid crystal
layer is the same as those of the above, whereby a detailed
explanation for the upper substrate 301a, lower substrate 301b, and
liquid crystal layer will be omitted.
In FIGS. 7 and 8, the second seal 301f indicates the seal formed in
the outermost portion of the first non-display area 301d of the
panel; and the first seal 301e indicates the seal formed along the
interface between the display area 360 of the panel and the first
non-display area 301d.
As shown in FIG. 7, the first seal 301e is extended from the third
seal 301m and the fourth seal 301n while being in parallel to the
second seal 301f; curved toward the second seal to surround the
transmitting part, and then connected with the second seal.
Meanwhile, since FIG. 8 illustrates the cross section surface along
B-B' of FIG. 7, the first seal 301e is expressed by a dotted
line.
As mentioned above, since the transmitting part is sealed by the
first seal and the portions of the second seal, the liquid crystal
is filled therein, and the vacuum part of the first non-display
area except the transmitting part is sealed under the vacuum state
by the use of first seal and second seal.
The reason why the transmitting part is filled with the liquid
crystal is to compensate for a concentric-circle shaped diffraction
pattern in accordance with diffraction of light passing through the
transmitting hole 301g by using a scattering property of liquid
crystal.
That is, the concentric-circle shaped diffraction pattern on the
image taken by the camera, and the spectrum mura shown on the
external of the panel may occur due to the diffraction of light
passing through the transmitting hole. These problems are solved
through the use of scattering property of liquid crystal by filling
the liquid crystal in the transmitting part between the
transmitting hole and the camera lens.
Especially, since a refractive index (n=1.54) of the liquid crystal
is similar to a refractive index (n=1.51) of glass for forming the
lower substrate and the upper substrate, the diffraction may be
decreased more, thereby resulting in the decreased diffraction
pattern on the image and the decreased spectrum mura on the front
of the panel.
In addition to the various shapes shown in FIGS. 7 and 8, the
various shapes of first seal surrounding the transmitting part may
be provided.
FIGS. 9 to 13 illustrate various shapes of first seal formed in the
panel of the display apparatus according to the fourth embodiment
of the present invention, which illustrate various examples of the
seal pattern in the periphery of the transmitting part, and
correspond to the expanded circle shape of FIG. 3.
First, the first seal 301e shown in FIG. 9 is extended from the
third seal and the fourth seal while being in parallel to the
second seal, wherein the first seal 301e is formed in the shape
surrounding the transmitting part.
That is, the transmitting part shown in FIG. 7 is surrounded by the
first seal and the portions of the second seal. Meanwhile, the
transmitting part shown in FIG. 9 is surrounded only by the first
seal 301e.
Then, the first seal shown in FIG. 10 extends from the third seal
and the fourth seal while being in parallel to the second seal, and
then surrounds the transmitting part. In this case, the first seal
301e being positioned adjacent to the second seal 301f is
overlapped with the second seal 301f.
That is, in case of the transmitting part shown in FIG. 7, one side
of the transmitting part is surrounded only by the second seal. In
case of the transmitting part shown in FIG. 10, the transmitting
part is surrounded by the first seal, wherein the predetermined
portion of the first seal 301e being adjacent to the second seal
301f overlaps with the second seal 301f.
Then, the first seal shown in FIG. 11 is identical in structure to
the first seal shown in FIG. 7. Additionally, the first seal is
formed between the transmitting part and the display area.
That is, the transmitting part shown in FIG. 11 is isolated from
the display area and the vacuum part by the first seal 301e and the
predetermined portion of the second seal 301f.
Then, the first seal shown in FIG. 12 is identical in structure to
the first seal shown in FIG. 9. Additionally, the first seal is
formed between the transmitting part and the display area.
That is, the transmitting part shown in FIG. 12 is isolated from
the display area and the vacuum part by the first seal.
Then, the first seal shown in FIG. 13 is identical in structure to
the first seal shown in FIG. 10. Additionally, the first seal is
formed between the transmitting part and the display area.
That is, the transmitting part shown in FIG. 13 is isolated from
the display area and the vacuum part by the first seal 301e, and
the overlapped portion between the first seal 301e and the second
seal 301f.
Among the above structures, the transmitting part penetrates the
display area by the first seal shown in FIGS. 7 to 10. Thus, in
case of the panel shown in FIGS. 7 to 10, the transmitting part may
be filled only with the liquid crystal.
However, the transmitting part is isolated from the display area
and the vacuum part while being sealed by the first seal shown in
FIGS. 11 to 13. Thus, in case of the panel shown in FIGS. 11 to 13,
the transmitting part may be filled with the other filling
materials in addition to the liquid crystal.
First, the transmitting part of the panel shown in FIGS. 11 to 13
may be filled with the filling material of the liquid crystal. In
the same manner as the liquid crystal injection method, an inlet is
formed in the first seal surrounding the transmitting part, and
then liquid crystal is injected via the inlet and the inlet is
sealed.
In this case, it is possible to prevent the foreign matters from
being collected in the transmitting part. That is, if the liquid
crystal is injected into the panel shown in FIGS. 7 to 10, the
foreign matters remaining between the lower substrate and the upper
substrate may be collected in the transmitting part, thereby
deteriorating the light transmittance. In case of the panel shown
in FIGS. 11 to 13, the transmitting part is separately sealed so
that this problem does not occur.
Then, the transmitting part of the panel shown in FIGS. 11 to 13
may be filled with liquid or gas whose refractive index is similar
to that of glass for forming the upper substrate and the lower
substrate.
The refractive index of glass is about 1.51. As shown in the
following Table 1, the transmitting part may be filled with various
liquid or gas materials (the following material) 301r whose
refractive index is similar to 1.51.
TABLE-US-00001 TABLE 1 Material Refractive index Ethyl Salicylate
1.52 Styrene 1.52 Methyl Salicylate 1.53 Sugared Water (80%)
1.49
Meanwhile, if the filling material 301r is the liquid or gas
material, in the same manner as the liquid crystal injection
method, an inlet is formed in the first seal for forming the
transmitting part, and then liquid or gas filling material is
injected via the inlet and the inlet is sealed.
If the filing material is a solid material, the filling material
manufactured in the same shape as that of the transmitting part may
be positioned in the transmitting part. Unlike the liquid crystal
layer, it is unnecessary to completely seal the transmitting part
by the first seal. That is, after injecting the solid filling
material by forming an inlet in the first seal for forming the
transmitting part, the first seal of the transmitting part may be
sealed.
That is, as mentioned above, the method for injecting the liquid,
solid, or gas filling material into the transmitting part sealed by
the first seal is to minimize the refraction of light passing
through the inlet by the use of filling material whose refractive
index is very similar to that of glass, thereby resulting in the
minimized light diffraction. Thus, it is possible to improve
visibility by decreasing the spectrum mura on the panel surface,
and to remove the concentric-circle shaped diffraction pattern from
the image taken by the camera.
Preferably, the refractive index of the above filling material 301r
is about 1.3 to about 1.7 in consideration to the diffraction
property.
FIG. 14 is another detailed cross section view illustrating a
display apparatus according to the fourth embodiment of the present
invention, which illustrates the detail of portion `D` of FIG. 2.
FIG. 15 is another plane view illustrating a panel applied to a
display apparatus according to the fourth embodiment of the present
invention. The first non-display area of FIG. 14 is exemplary shown
in FIGS. 9 to 13.
As shown in FIG. 14, another shape of the display apparatus
according to the present invention includes the first seal 301e
which is provided for the division between the display area 360 of
the panel and the first non-display area 301d. If the first
non-display area is not filled with the liquid crystal (vacuum
state), a transmitting-hole column spacer 301t whose structure is
the same as that of a column spacer 301s in the display area is
formed in the transmitting hole 301g made by removing the black
matrix 301k.
Herein, the transmitting-hole column spacer 301t may be formed of
the solid filling material that has been described above with
reference to FIGS. 11 to 13. That is, the transmitting-hole column
spacer 301t is formed of a material having a refractive index
similar to that of the glass, and thus removes a spectrum-shaped
concentric circle by decreasing the diffraction of light passing
through the transmitting hole.
The transmitting-hole column spacer may be manufactured together
with the column spacer 301r formed in the display area. In this
case, as a height of the transmitting-hole column spacer 301t
becomes higher than a height of the column spacer in the display
area by the use of halftone mask, the transmitting-hole column
spacer may contact with the upper substrate and the lower
substrate. However, since there is the small gap between the upper
substrate and the lower substrate, it is allowed that the
transmitting-hole column spacer is formed at the same height as
that of the column spacer in the display area by the same
process.
As shown in FIG. 15, under the circumstance that the peripheral
region of the transmitting hole is not surrounded by the first
seal, the transmitting-hole column spacer is formed in the
transmitting part. As shown in FIGS. 7 to 11, the transmitting-hole
column spacer formed in the transmitting part may vary in
shape.
That is, as shown in FIGS. 7 to 10, the transmitting-hole column
spacer 301t may be surrounded by the first seal under the
circumstance that the transmitting part penetrates through the
display area. As shown in FIGS. 11 to 13, the transmitting-hole
column spacer may be isolated from the display area and the vacuum
part while being sealed.
Thus, if the transmitting-hole column spacer is formed in the
transmitting part as shown in FIGS. 7 to 10, the transmitting part
is filled with the liquid crystal.
FIG. 16 is another detailed cross section view illustrating a
display apparatus according to the fourth embodiment of the present
invention. Except the structure of first panel supporter 204a, the
display apparatus shown in FIG. 16 is identical in structure to the
display apparatus shown in FIGS. 7 to 15, whereby a detailed
explanation for the same part will be omitted.
Except the structure of the first panel supporter 204a having the
camera receiving part, the display apparatus shown in FIG. 16 is
identical in structure and function to the display apparatus shown
in FIGS. 7 to 14.
That is, as mentioned in the above explanation with reference to
FIG. 2, the first panel supporter 204a may be formed in the
`.andgate.` shape or `.orgate.` shape. FIG. 16 illustrates the
`.orgate.`-shaped first panel supporter.
Thus, except the first panel supporter, the display apparatus shown
in FIG. 16 is identical in structure to the display apparatus shown
in FIGS. 7 to 15, wherein the transmitting part may vary in shape,
as mentioned above.
That is, in case of the display apparatus according to the fourth
embodiment of the present invention, the transmitting part inside
the panel 301 is filled with the various kinds of filling material,
to thereby decrease the diffraction pattern on the image taken by
the camera, and the spectrum mura shown on the plane of the panel.
The structure of the transmitting part may be manufactured in
various shapes, as mentioned above.
In addition, since the transmitting hole generates the
concentric-circle shaped diffraction pattern by the diffraction of
light, the spectra mura to be shown by the naked eyes occurs in the
periphery of the transmitting hole, and the concentric-circle
shaped diffraction pattern is shown on the image taken by the
camera. In case of the display apparatus according to the fourth
embodiment of the present invention, the transmitting part in the
periphery of the transmitting hole is sealed by the use of seal,
and is then filled with the various kinds of the filling material,
thereby preventing the above diffraction phenomenon. Thus, it is
possible to remove the spectra mura shown by the naked eyes, and to
remove the diffraction pattern from the image taken by the
camera.
For this, the display apparatus according to the fourth embodiment
of the present invention uses the following two methods.
The first method is to scatter the light passing through the
transmitting hole and advancing toward the camera lens by filling
the transmitting part with the filling material having the
scattering property, for example, the liquid crystal.
The second method is to decrease the refraction and diffraction of
the light passing through the transmitting hole and advancing
toward the camera by filling the transmitting part with the solid,
liquid, or gas filling material whose refractive index is similar
to that of the glass for forming the panel. In case of the solid
material, it is possible to apply the transmitting-hole column
spacer whose shape is the same as that of the column spacer for
maintaining the cell gap between the upper substrate and the lower
substrate. The liquid glass material may be injected into the
transmitting part, and be coagulated therein. Also, the solid glass
material may be attached to the transmitting part.
For filling the transmitting part with the various kinds of filling
material in the display apparatus according to the fourth
embodiment of the present invention, the peripheral region of the
transmitting part may be sealed in various shapes by the use of
seal.
In the display apparatus according to the fourth embodiment of the
present invention, the depression is not generated in the periphery
of the transmitting part since the peripheral region of the
transmitting hole is surrounded by the seal, or filled with the
filling material, thereby preventing the mura defect from the
predetermined portion of the display area being adjacent to the
transmitting hole.
Accordingly, the liquid crystal is injected into the non-display
area having the transmitting hole formed in the predetermined
portion of the panel corresponding to the camera, or the column
spacer is formed in the non-display area having the transmitting
hole formed in the predetermined portion of the panel corresponding
to the camera so as to prevent the depression of the upper
substrate, thereby preventing the depression of the upper substrate
in the periphery of the transmitting hole, and preventing the mura
from the display area.
Also, the transmitting part having the transmitting hole formed in
the non-display area of the panel corresponding to the camera is
sealed by the use of seal, and then the inside is filled with any
one filling material of solid, liquid, and gas. Thus, the inner
refractive index of the transmitting part having the transmitting
hole is similar to the refractive index of the substrate so that it
is possible to prevent the diffraction in the periphery of the
transmitting hole, and to prevent the diffraction pattern from the
image taken by the camera.
It will be apparent to those skilled in the art that various
modifications and variations can be made in the present invention
without departing from the spirit or scope of the inventions. Thus,
it is intended that the present invention covers the modifications
and variations of this invention provided they come within the
scope of the appended claims and their equivalents.
